The short answer: honeycomb paperboard pallets and skids are exempt from ISPM 15 because they are processed wood-based products, not solid wood packaging material. That exemption removes heat treatment cost, the IPPC stamp requirement, and the risk of a shipment being refused or fumigated at a foreign port. Add a four-to-one weight advantage over wood and the case for one-way export is usually decisive — provided the load is within the deck’s sustained capacity.
ISPM 15 is the international standard governing wood packaging material in trade. It exists to stop pests such as the emerald ash borer and pine wood nematode traveling in raw wood. Solid wood packaging thicker than 6 mm — pallets, crates, dunnage, bracing — must be heat treated or fumigated and marked with the IPPC stamp.
The standard explicitly exempts processed wood-based products manufactured using glue, heat and pressure. Honeycomb paperboard falls squarely in that category: the fiber has been pulped, reformed and bonded, and the process eliminates any pest risk.
The practical consequence is that a honeycomb pallet or skid crosses borders without treatment, without a stamp, and without the documentation trail that goes with them.
| Cost or risk | Heat-treated wood pallet | Honeycomb pallet |
|---|---|---|
| Treatment and certification | Required, per pallet | Not applicable |
| Stamp verification before loading | Required | Not applicable |
| Risk of port refusal or fumigation | Real, and expensive when it happens | Eliminated |
| Weight, 48×40 | 35–50 lb | 8–14 lb |
| Air freight cost impact | High | Low |
| Container cube when nested | Poor | Excellent — ships flat |
| Nails and splinters at receiving | Present | None |
| Disposal at destination | Wood waste stream | OCC bale |
The line that surprises most exporters is the third one. A container held at destination over a wood packaging non-conformity generates demurrage, re-treatment or destruction costs and a delivery failure — a low-probability, high-consequence exposure that disappears entirely with a paper deck.
Honeycomb decks are a one-way export solution. That is not a limitation so much as a definition of the use case.
Good fit: one-way export shipments, air freight where every pound counts, clean-environment operations where wood is unwelcome, pharmaceutical and food applications, and any lane where the pallet will not come back.
Poor fit: pooled pallet systems, high-reuse internal loops, outdoor storage, wet environments without coating, and very heavy or highly concentrated point loads.
The correct comparison is not honeycomb against a pooled pallet in a domestic loop. It is honeycomb against a one-way heat-treated wooden pallet that will be discarded at destination anyway — and in that comparison the paper deck usually wins on weight, cube, cost and compliance simultaneously.
Honeycomb pallet capacity is quoted in three different ways, and the differences matter.
Static load — what the pallet holds sitting on a flat floor. The largest number and the least useful.
Dynamic load — what it holds while being moved by forklift or pallet jack, where the load is carried on the fork tines rather than the full deck.
Racked load — what it holds spanning between beams with no support in the middle. The smallest number by a wide margin, and the one that matters if your customer racks incoming pallets.
A deck rated for 2,000 lb static may be rated for 1,200 lb dynamic and considerably less racked. Ask which figure you are being quoted and specify the one your application requires. Also apply the sustained-load derating discussed for honeycomb generally: a pallet holding a load for six weeks in a warehouse is a creep case, not a static case.
The lightest option. Runners are honeycomb tubes or folded sections. Suits air freight and light to medium loads.
A hybrid. Note that the wood runners are solid wood and therefore do fall under ISPM 15 — a detail that catches exporters out. If the compliance advantage is the reason for the change, the design has to be all-paper.
Eliminates the pallet entirely where push-pull handling is available. Best cube efficiency in a container by a wide margin.
Because there is no tooling, a honeycomb skid can be cut to the actual product footprint rather than to a standard pallet size. On irregular products this often removes a full inch of overhang on each side, which compounds into container fit.
Exporters focus on the ISPM 15 saving and frequently miss a larger one.
A wooden pallet is roughly 5.5 inches tall. A honeycomb deck can be 1.5 to 3 inches. In a standard container with a fixed internal height, that difference sometimes permits an additional layer of product per stack — a several-percent increase in payload per container on the same freight cost.
Run the arithmetic for your specific product height before assuming it does not apply. On tall, light products it rarely helps; on short, dense products it frequently does, and it is worth considerably more than the treatment cost saved.
The main technical objection to paper pallets is legitimate. Ocean containers reach very high relative humidity with condensation cycles, and uncoated fiber loses roughly half its stiffness under those conditions.
Three measures address it. Specify a water-resistant adhesive rather than standard PVA. Specify a coated face — poly or a Nomar-type treatment — on the deck surface that contacts the load and on the underside that contacts the container floor. And use desiccants inside the container, which is standard practice for moisture-sensitive cargo regardless of pallet material.
With those three in place, honeycomb decks perform reliably on transpacific and transatlantic lanes. Without them, they will disappoint — and the failure will be attributed to the material rather than to the specification.
A short qualification sequence prevents the common failure of testing a paper deck under conditions it was never specified for.
Start by defining the load case honestly: weight, footprint, whether it will be racked, and how long it will sit. Then confirm the handling equipment at every point in the chain, including at destination, since a deck designed for fork entry on two sides will frustrate a receiver who approaches from the other axis.
Run a static load test at design weight for the expected dwell, not for an hour. Then ship a trial container with the pallets photographed on loading and inspected at destination. Six to eight weeks produces a reliable answer, and the humidity behavior is the part you cannot predict from a datasheet.
The compliance argument is the headline, but the money usually comes from three other lines. Running them for a real lane makes the decision straightforward.
Air freight weight. At typical transpacific air rates, removing 30 lb of pallet weight per unit load saves a meaningful amount per shipment. On a program running weekly air shipments, this line alone often exceeds the entire pallet cost.
Container payload. Where a lower deck height permits an extra product layer, the saving is the marginal cost of a container divided across the additional units. This is the largest single line when it applies.
Treatment and administration. Heat treatment per pallet, stamp verification labor, and the occasional non-conformity event. The last is low probability and high consequence, which makes it easy to leave out of a spreadsheet and expensive to leave out of a decision.
Against those, the material cost difference between a heat-treated one-way wooden pallet and a honeycomb deck is usually modest and sometimes favors paper outright.
Eight lines make quotes comparable and prevent the most common disappointments: deck dimensions and tolerance; required load rating stated as static, dynamic or racked; expected dwell under load; fork entry configuration and runner spacing; humidity exposure and required coating; adhesive type; stacking configuration in the container; and whether the receiver uses conveyors, racking or clamp handling.
Suppliers who answer all eight in writing are quoting the same thing. Suppliers who quote a price against “48×40 honeycomb pallet” are not.
No IPPC mark is required because they are exempt. Some exporters add a printed statement identifying the material as a processed wood-based product, which can smooth questions at inspection even though it is not mandated.
Yes. The exemption for processed wood-based products is part of the ISPM 15 standard itself and is applied by national plant protection organizations accordingly.
Deck flatness and runner spacing determine this, not material. Specify the conveyor and racking requirements up front, since a deck designed for forklift handling may not have the runner geometry a conveyor needs.
Uncoated fiber loses capacity quickly and should be treated as compromised. This is a real operational constraint: paper pallets need indoor staging, and any operation that leaves pallets outdoors should coat them or choose a different solution.
For one-way export, honeycomb pallets and skids remove an entire compliance obligation, cut pallet weight by three quarters, and often improve container fit. The constraints — moisture, racked load and outdoor storage — are real but specifiable. The mistake to avoid is comparing a paper deck against a pooled pallet in a domestic loop rather than against the one-way treated pallet it actually replaces.
